First up, the bug: When I click on "Gateways and Providers" and then atempt to edit a 3cx bridge-to-bridge device, I am thrown this error: Fatal error: Call to a member function getStunHost() on a non-object in c:\program files\3cxphonesystem\data\http\voip_gateway2.php on line 105 Also, I can't shut the STUN server error messages up. Because I run on a fixed IP and have things configured on my router such that I don't need STUN, it's annoying, to say the least. Now, on to the real problem. I want to be able to test the Fax featues on this new version of 3cx, as well as test the 3cx bridge connections. However, fax support for these seems to be disabled. I can turn fax support on for other VOIP lines, just not for the bridge connections. Does anyone have a workaround for this? A way to link 2 3cx PBX instances such that calls can be passed between them?
